Design And Implementation Of Dynamic Protocol Module In IIP System

For a long time, the voice call is the core service of telecom networks, network design takes the phone business as the optimization goal. But the rapid development of the Internet broke this rule. The proportion of data business carried on the telecom networks is increasing. Broadbrand data services become the main source for the telecom operators income growth. According to this trend, the IP protocol of the Internet will dominate the telecom network. IP networks with flexibility, scalability and high availability have been a great challenge to thetraditional telecom networks. Modern communication networks is more and more dependent on IP networks. Network of IP has become irreversible trend.Independent Intelligent Peripheral(ⅡP) is one of the important entities of intelligent networks. ⅡP has the capability of Special Resource Function(SRF) provides resource service to the terminal in the intelligent networks. For example, sendsprompt to the users, receives the user’s dial, etc.Under the current trend of IP-based telecom network, the deficiencies of IIP system has been apparent. Currently, the degree of couplingof the CMIN02-IIP system’s Control Node between architecture and protocol is high. The implementation of the protocol scatters among the program. We must modify the entire program for each additional protocol. It is difficult for development and maintenance. This paper proposes an improved scheme to solve this problem. We separate the implementation ofthe existing related protocols from the main program, and implement it in the dynamic link library which only provides the related part of the protocols. The operations of every protocol is controlled through the management class,which leads to a result that the maintainability, scalability and security of the ⅡP system is enhanced, and difficulty of development is reduced.
